A prototype of hydraulically operated coconut oil extractor was designed and fabricated. The machine can be used for other oil-bearing seeds such as groundnut and palm kernel. The machine is made up of a plunger, ram disc, expression chamber, and electric heater. The extractor can process 10kg coconut per hour.

An efficiency of 15% was obtained from the coconut cake of 2.9kg (wet basis). While for the dry basis 40% of oil was obtained from coconut cake of 2.5kg.
